Sync command line output for Slurm with RSH launcher.
Currently Slurm launch cmdline will only be visible in debug mode, while for RSH
it is enabled always.
cmdline makes sense for troubleshooting and should be enabled.

Warn that relative path will be converted to absolute path, meaning that the file system on remote nodes must be the same as on the node where mpirun is executed.

Since we now support the dynamic addition of hosts to the orte_node_pool, there is no longer any reason to require advanced specification of all possible nodes. Instead, use a precedence method to initially allocate only those hosts that were specified in the cmd line:
* rankfile, if given, as that will specify the nodes
* -host, aggregated across all app_contexts
* -hostfile, aggregated across all app_contexts
* default hostfile
* assign local node
Fix slots_inuse accounting so that the nodes are correctly reset upon error termination - e.g., when oversubscribed without permission.
Ensure we accurately track the user's specified desires for oversubscribe and no-use-local when dynamically spawning jobs.

(cherry picked from commit c9b3e68ce596a68a2ed2fbf73f211b3334b0a6a8)
Fixed the desync of job-nodelists between mpirun and orted
daemons. The issue was observed when using RSH launching because user
can provide arbitrary order of nodes regarding HNP placement.
The mpirun process propagate the daemon's nodelist order to nodes.
The problem was that HNP itself is assembling the nodelist based on
user provided order. As the result ranks assignment was calculated
differently on orted and mpirun.
Consider following example:
* User launches mpirun on node cn2.
* Hostlist is cn1,cn2,cn3,cn4; ppn=1
* mpirun is passing hostlist cn[2:2,1,3-4]@0(4) to orteds
So as result mpirun will assing rank 0 on cn1 while orted will assign
rank 0 on cn2 (because orted sees cn2 as the first element in the node
list)

When too much data is available on stdin, it might not be
forwarded immediatly to the task (write() might fail with -EAGAIN),
so when stdin is terminated, there might be some remaining data
to be pushed to the task. In this case, delay the release of the sink
so no data is discarded.

Fix a problem in packing/unpacking job updates. There remains a race condition that causes messages to attempt to be sent to the second new daemon before it is completely ready. Not entirely sure where it is coming from.

Search for the digits to be compressed from the end of the node names.
For example, if the nodelist is c712f6n01,c712f6n02,c712f6n03
the regx/fwd component generates c[3:712]f6n01,c[3:712]f6n02,c[3:712]f6n03@(3)
when the regx/reverse component generates c712f6n[2:1-3]@0(3) which is
a better fit here.

Resolve a race condition between registering for a file to be removed upon termination and actual creation of that file by providing attributes that identify whether the path is a file or directory. This removes the need for PMIx to detect the difference.

Handle the need for different regex generator/parsers by moving the

Use the original code to complete a "fwd" component, and create a

Now that the daemon calls remote_spawn itself, there is no longer
a need for the "tree_spawn" command nor the associated command
processing code since the HNP is no longer sending a tree-spawn

Somehow, the code for passing a daemon's parent was accidentally removed, thus breaking the tree-spawn callback sequence and causing all daemons to phone directly home. Note that this is noticeably slower than no-tree-spawn for small clusters where directly ssh launch of the child daemons from the HNP doesn't overload the available file descriptors.

Only selectable when specifically requested via "-mca odls pspawn"
Note that there are several concerns:
* we aren't getting SIGCHLD calls when the procs terminate
* we aren't seeing the IO pipes close on termination, though
we are getting output forwarded to mpirun
* I haven't found a way to bind the child process prior to exec.
If we want to use this method, we probably need someone to
implement a cgroup component for the orte/rtc framework

Change the determination of #spawn threads to be done on basis of #local procs in first job being spawned. Someone can look at an optimization that handles subsequent dynamic spawns that might be larger in size.
Leave the threads running, but blocked, for the life of the daemon, and use them to harvest the local procs as they terminate. This helps short-lived jobs in particular.
Add MCA params to set:
* max number of spawn threads (default: 4)
* set a specific number of spawn threads (default: -1, indicating no set number)
* cutoff - minimum number of local procs before using spawn threads (default: 32)

The current error message when the number of slots is insufficient
(e.g. running mpirun -n 4 on a dual core machine) does not mention the
use of `--oversubscribe`.
In earlier version of Open MPI, the over-subscription was automatic
(albeit buggy?); but the important point was no error message was
printed and the application runs. Mentioning the oversubscibe flag in
the message will ease up the transition to the current behaviour where
explicit request is required.
Also make a few other minor tweaks / cleanups to the
orte-rmaps-seq:alloc-error help message.
